I am running Bobcam V25 on a Bridgeport EZtrak SX. I am having problems with the machine wanting to run jerking through a program around arcs or anytime it changes direction. I take the Gcode program directly from Bobcam and save it to a floppy disk as a .txt file and run it in the machine. I have read about the g64 and g61 commands used in Mach3 however I do not have mach3. I have changed the Arc Slowdown and that seems to have no change on things. Has anyone else had this problem or know how to solve it? Any help is appreciated. I know very little about gcode but I have attached a program that may offer some help. Thanks
